External wall thermal insulation board

Abstract

The invention provides an external wall thermal insulation board which comprises a fire-retardant layer used as a base layer, a thermal insulation layer arranged on the outer side of the fire-retardant layer, an external decoration plate arranged on the outer side of the thermal insulation layer and a connecting pin plate which is consistent with the external wall thermal insulation board in thickness. The end of the fire-retardant layer, the end of the thermal insulation layer and the end of the external decoration plate are arranged to be in a groove shape. The fire-retardant layer and the external decoration plate are provided with protrusion edge parts, and the thermal insulation layer is provided with an inward-concave part. A positioning through hole is formed in the protrusion edge part of the external decoration plate. The cross section of the connecting pin plate is in a crossed shape, and the side portion of the connecting pin plate is matched with the groove of the external wall thermal insulation board. A fixing hole is further formed in the corresponding position of the positioning through hole of the external decoration plate. The connecting pin plate is matched with the groove of the thermal insulation board, plugging is convenient, construction is fast and convenient, the engineering labor intensity and difficulty are low, the construction period is shorter, the external wall thermal insulation board is fixed into the fixing hole through a screw and the positioning through hole, fixing is firm, and disengaging is not likely to happen in long-time using.

Description

technical field [0001] The invention belongs to the field of building wall materials, in particular to an external wall thermal insulation board. Background technique [0002] At present, styrene boards on exterior walls are usually used for thermal insulation in the construction industry. In the process of renovation, it is necessary to consider the simplicity and effectiveness of construction, as well as building energy conservation, environmental protection and intensification. In order to overcome the technical problems of complicated construction, long construction period, and easy to fall off in large areas, it is necessary to redesign the connection method of the external wall insulation board. SUMMARY OF THE INVENTION [0003] The problem to be solved by the present invention is that the construction of the external wall thermal insulation board is complicated and easy to be detached in a large area, and is especially suitable for the reconstruction and constructio...
